How long can a CO2 extinguisher operate continuously?

A CO2 extinguisher is designed to expel carbon dioxide gas under high pressure and is commonly used for various types of fires, particularly electrical and flammable liquid fires. The discharge time of a CO2 extinguisher is a crucial factor for effective firefighting, as it dictates how long the operator can apply the agent to the fire.

When a CO2 extinguisher is deployed, it typically has a continuous operation duration of around 40 seconds, which allows the operator sufficient time to target the flames effectively. This duration is important, especially given the nature of the extinguishing agent, which can displace oxygen in the environment and requires careful application to avoid hazards.

Understanding the operational limits of the extinguisher is essential for safety and effectiveness. This time frame enables users to manage the extinguisher appropriately without running out of agent too quickly, thereby maximizing its effectiveness in cooling and smothering the fire.
